We compare the imbibition of an aqueous surfactant solution into an oil-wet pore driven by surfactant adsorption onto the oil-wet rock surface (coating mechanism) and the imbibition of an aqueous surfactants solution driven by surfactants removing the contaminant molecules from the originally water-wet surface (cleaning mechanism). Our results show qualitative difference in the imbibition dynamics in these two cases and indicate that MD simulation is a useful tool to investigate details of the imbibition mechanisms at the pore scale with direct implications for Enhanced Oil Recovery (EOR) operations. 5 Oil and Gas Science and Technology 67 ARTICULO Stukan, M.R. 53112 Ligneul, P. 53113 Boek, E.S. 53114 187661 187661 0 0 0 0 255480 BAAB BAAB 2026-03-06 200059796 0 200059796 2026-03-06 00:17:37 2026-03-06 ARTICULO
